CHCO‚ Natural Gas & Carbon Monoxide Detector
The CHCO is a dual sensor, gas and carbon monoxide detector.
The CHCO is a dual sensor, gas and carbon monoxide detector. When methane and/or carbon monoxide are sensed the detector audible alarm sounds. A volt free contact relating to the type of gas sensed. These relays can be used to isolate the gas solenoid valves electrical supply or give remote indication. The alarm setpoint for methane is 10% LEL and for carbon monoxide is 300ppm. The CHCO has a separate relay alarm facility which gives an output at 30-50-100ppm of CO based on time weighted average.
